I just bought 1kg (for the year) of micronised Creatine. Micronised just dissolves better as it's fine powder vs unmicronised which clumps in the water and is grainy.

The packaging was just a brown plastic lined paper bag, but inside is the good stuff, so looks don't always translate to value (it was cheaper and better quality too).

Most, if not all, is the same, you just pay for branding and some plastic tubs, especially from these sports shops.

Always read the ingredients; some brands mix sugar, whey and other stuff like glucose into it to make "power mixes" or whatever shit.
